The right answer is organelle G, which represents mitochondria.
Mitochondria is the place of cellular respiration. This is a set of reactions that convert glucose into the energy molecule, ATP. This process involves several steps, including the "Krebs Cycle", a set of metabolic reactions that takes place in the mitochondrial matrix. The enzyme that produces ATP is found in the inner membrane of the mitochondria. For these reasons, the mitochondria is often referred to as the cell's energy factory.
Answer:
3. shapes the genetic characteristics of a species as a consequence of adaptation
Explanation:
Natural selection is a process characterized by how plants and animals that are able to adapt to changes in their environment are able to survive and reproduce while those that are unable to adapt do not survive.
In natural selection, those variations in the genotype which increases an organism’s chances of survival and procreation are preserved and multiplied from generation to generation at the expense of less advantageous variations.
Natural selection is a way of enhancing the preservation of a group of organisms that are best adjusted to the physical and biological conditions of their environment and may also result in their improvement in some cases.
<span>Catabolism is all of the chemical reactions that break down molecules, either to extract energy or to produce simple molecules for constructing others. Anabolism refers to all of the metabolic reactions that build or assemble more complex molecules from simpler ones.</span>
Chromatids are only called as chromatids when they are sister chromatids, meaning that when chromosome have two double stranded DNA attached together, each of the double stranded DNA is a sister chromatid, and while the whole thing (the two sister chromatids that are attached together) is called a chromosome.
So after the DNA has been replicated, the chromosome consist of 2 sister chromatids, attached to each other at their centromere.
Overall, sister chromatid is one of the two double stranded DNA in a replicated chromosome, and chromosome is the whole "X" shape that we see. For example, in humans, after the S phase of interphase in the cell cycle, we have 46 chromosomes, with 92 chromatids, since each chromosome is an "X" shape, by having two sister chromatids.
Hope this helps!
